Abstract
The addition of suerose monotallowate to an aqueous solution of alkanolamine alkylaryl sulfonate lowers the total active-agent content required for the formation of liquid crystals. In contrast, the addition of polyoxyethylene esters of fatty acids to the alkylaryl sulfonate solution increased the total amount of active agent required for the formation of liquid crystals. The deaggregating effect of the ethylene oxide-derived nonionies was reflected in reduced foam and detergeney for combinations of these nonionics and alkylaryl sulfonate. Foam and detergeney remained at a high level with combinations of sucrose monotallowate and alkylaryl sulfonate. Higher hydrophile-lipophile balance (HLB) values were obtained with the sugar esters than with the polyoxyethylene nonionics. The results were examined in terms of Winsor’s theory of intermicellar equilibria.
